Subject: Re: CVE request: mongodb: world-readable .dbshell history file

-----BEGIN PGP SIGNED MESSAGE-----

> 
> | During the report on redis-tools
> | (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=832460), lamby@
> | linked to a codesearch and the same bug was found in mongodb-clients.
> |
> | mongodb-clients stores its history in ~/.dbshell, this file is created
> | with permissions 0644. Home folders are world readable as well in
> | debian, so any user can access other users mongodb history, even though
> | db.auth commands don't appear to be logged like redis did.
> |
> | I filed a bug on upstream as well:
> | https://jira.mongodb.org/browse/SERVER-25335
> 
> The mongodb client doesn't store authentication commands, but there's
> still information leakage, though, even if only about database and
> collection names, or data structure.
> 
> As for data itself, the history could also contain sensitive
> information; for instance, if usernames for some other service were
> stored in a mongo collection, the history could contain lines like:
> 
>   db.users.find({user:"foo"})
> 
> or even:
> 
>   db.users.update({user:"foo"},{$set:{password:"OhComeOnNow"}})
